By tuning the deposition parameters of reactive high-power impulse magnetron sputtering, specifically the pulse length, we were able to prepare WO3-x films with various stoichiometry and structure. Subsequently, the films were annealed in air at moderate temperature (350 °C). We demonstrate that the stoichiometry of the as-deposited films influence...

In this work, PdOx-CuOx co-loaded porous WO3 microspheres were synthesized with varying loading levels by ultrasonic spray pyrolysis (USP) using polymethyl methacrylate (PMMA) microspheres as a vehicle template. The as-prepared sensing materials and their fabricated sensor properties were characterized by X-ray analysis, nitrogen adsorption, and el...

Here, the splitting of water from humidity at the surface of WO 3 is reported. The production of hydrogen occurs under mild conditions, at 300 °C in the presence of humidity. Using operando diffuse reflectance infrared Fourier transform spectroscopy and DC resistance measurements complemented with DFT calculations, it was possible to elucidate the ...

Glasses with composition [xWO3–(25−x)–ZnO–20Na2O–55B2O3 where x = 0, 5, 10, 15 and 20 mol. %] were prepared by melt quenching method. The amorphous state of the current glass samples was checked by X-ray diffraction (XRD). The measured density and calculated molar volume of all prepared samples were found to increase with the replacement of the lig...

The bi-functional [email protected] catalysts were prepared by one-pot reduction-carbonization method and used in hydrogenolysis of cellulose as well as raw lignocellulosic biomass to chemicals. The catalytic performance for cellulose conversion showed that it was more favorable for ethylene glycol (EG) production, obtaining the highest EG yield 60.1% over th...

Photocatalytic ozonation (light/O-3/photocatalyst), an independent advanced oxidation process (AOP) proposed in 1996, has demonstrated over the past two decades its robust oxidation capacity and potential for practical wastewater treatment using sunlight and air (source of ozone). However, its development is restricted by two main issues: (i) a lac...

In this study, a photocatalyst S-doped WO3 was successfully synthesized by the hydrothermal method. The prepared undoped and S-doped WO3 samples were then characterized by XRD, SEM, XPS, and UV-vis DRS. The results showed that the band gap energy of S-doped WO3 was lower than that of the undoped WO3, which led to a better absorption of visible ligh...

Gas sensors are an important part of smart homes in the era of the Internet of Things. In this work, we studied Ti-doped P-type WO3 thin films for liquefied petroleum gas (LPG) sensors. Ti-doped tungsten oxide films were deposited on glass substrates by direct current reactive magnetron sputtering from a W-Ti alloy target at room temperature. After...
